I thought the Cinematography was especially horrible throughout the film. Every scene that should have appeared darker simply looked artificially lit up. Most cheap DTV films have better cinematography than this film did!

I agree with this. But, I wonder if Argento was trying to compensate for the lost light resulting with the 3D glasses. Granted, that implies that at least some thought went on while this was being made and I really don't see much evidence of that anywhere else.

It also seems like the actors didn't know that camera was running. At times, it seems like everyone thought this was a dress rehearsal.
